Definitions
- the present invention relates to a process for treating a yarn and/or a fabric to form a fine inorganic particulate material in the intra-yarn pores and/or on the surfaces of the fibres constituting the yarn or fabric, which would substantially maintain fabric reflectance after repeated wash/wear cycles without affecting the desired characteristics of air permeability.
- the invention also relates to a treatment product composition directed to provide instant inorganic deposits in the yarn or fibre surface.
- yarns used for producing fabrics and the fabrics so obtained have pores.
- the yarns per se have inter-fibre pores while the fabric obtained of such yarn apart from such inter-fibre/intra-yarn pores also have inter-yarn pores. It is found that during use of the fabric, particulate soils and/or oily soils get trapped in the minute intra-yarn pores which get firmly bonded to the yarn or fabric.
- An unsoiled new fabric generally has a reflectance value of about 88 when measured at a wavelength of 460 nm with UV filter. It is found that following soiling and wash regimes, fabric reflectance may drop to below 65 leading to greying of the fabric. It is established that smaller dirt/soil particles pose a serious challenge in terms of their removal since they accumulate in intra-yarn pores and on the fibre surface. Such small soil particles deposited in or on the fabric are the main cause for decline in fabric reflectance.
- WO 9842909 discloses a fabric with UV blocking particles bound to the fabric by binding agents. It discloses the process of deposition followed by heat treatment.
- the present inventors have surprisingly found that a fabric or yarn which comprises fine particulate inorganic particles either on the surface or in the pores of the fibres maintains the fabric reflectance after repeated wash/wear cycles without affecting the desired characteristics of air permeability.
- the present invention provides a process for the production of a treated textile yarn or fabric which comprises treating the yarn or fabric with at least two reagents capable of reacting together to form a fine inorganic particulate material, whereby the fine inorganic particulate material is precipitated in the intra-yarn pores and/or on the surfaces of the fibres constituting the yarn or fabric.
- the invention provides a treatment product comprising at least two separate ingredients capable of reacting together in an aqueous medium to form a fine inorganic particulate material, preferably having a particle size not exceeding 5 ⁇ m.
- the fine inorganic particulate material in the intra-yarn pores and/or on the fibre surface can be provided by reacting in an aqueous medium a first reagent selected from mineral and organic acids and a second reagent selected from alkali or alkaline earth metal salts with inorganic anions.
- the mineral acid may be selected from hydrochloric acid, sulphuric acid, nitric acid or phosphoric acid. If hydrochloric acid is used it is preferably at a concentration of from 0.1 to 0.8 gmol/l. If phosphoric acid is used it is preferably at a concentration of from 0.02 to 0.2 gmol/l.
- the inorganic anion may be selected from silicate, aluminate, carbonate, hydroxide, phosphate, chloride, sulphate or nitrate and preferably aluminate or silicate.
- the process of producing the treated fabric/yarn comprises:
- step (a) the yarn or fabric is treated with the reagent solution having the lower diffusion coefficient. This is to prevent the first reagent from coming out of the intra yarn pores when the second reagent is added to the yarn or fabric.
- the second reagent with higher diffusion coefficient penetrates into the intra yarn pores and reacts with the first reagent which is already present there.
- the process of producing the treated fabric or yarn comprises treating the fabric or yarn with an aqueous solution of alkali metal silicate and urea whereby silica is precipitated in the intra-yarn pores and/or on the surfaces of the fibres constituting the yarn or fabric.
- such a process comprises treating the yarn or fabric with a dilute alkali metal silicate solution, through which CO 2 is bubbled, whereby silica is precipitated in the intra-yarn pores and/or on the surfaces of the fibres constituting the yarn or fabric.
- the process of producing the treated fabric/yarn comprises treating the yarn or fabric with a dilute alkali metal silicate solution followed by drying the yarn or fabric in air, whereby silica is precipitated in the intra-yarn pores and/or on the surfaces of the fibres constituting the yarn or fabric.
- the drying is carried out for a period of at least two hours such that complete conversion of the alkali metal silicate into silica is achieved.
- the deposition of silica is dependent upon the concentration of the alkali metal silicate solution as well as the drying time and the deposition can be varied depending upon the desired end deposit on the yarn/fabrics.
- yarn or fabric treated by the above process has deposits of fine inorganic particulate material providing for reduced soiling of fabrics, including oily soils, and maintaining higher reflectance in repeated wear/wash cycles.
- the yarn or fabric treated by the above process has selective deposition of the particulate material only in the small intra-yarn pores and not in the inter-yarn regions which provides firstly, the maintenance of fabric reflectance even after repeated wash/wearing cycles is achieved and secondly, the desired air permeability through the fabric pores is maintained to provide comfort in use or wearing of the fabric.
- the second aspect of the present invention is a treatment product which comprises at least two separate ingredients capable of reacting together in an aqueous medium to form a fine inorganic particulate material, preferably having a particle size not exceeding 5 ⁇ m. It is preferred that the product comprises (a) at least one first ingredient selected from mineral and organic acids and (b) at least one second ingredient selected from alkali or alkaline earth metal salts with inorganic anions wherein (a) and (b) are capable of reaction in an aqueous medium to form a fine inorganic particulate material.
- the product is preferably accompanied with an instruction manual detailing directions of use of the product for carrying out in-situ deposition of the inorganic particulate material in the intra-yarn pores and/or on the surfaces of the fibres constituting the yarn or fabric.
- the constituent (a) of the product is preferably a mineral acid, preferably selected from, hydrochloric acid, sulphuric acid, nitric acid and phosphoric acid.
- (a) is an organic acid, preferably selected from citric acid, acetic acid and lauric acid or a combination thereof.
- the constituent (b) of the product is selected to have an inorganic anion selected from alkali metal silicate, aluminate, carbonate, hydroxide, phosphate, chloride, sulphate or nitrate and preferably aluminate or alkali metal silicate.
- ingredient (a) comprises hydrochloric acid in a concentration of from 0.1 to 0.8 gmol/l and (b) comprises sodium aluminate in a concentration of from 0.1 gmol/l to 0.8 gmol/l.
- ingredient (a) comprises phosphoric acid in amount of 0.02 gmol/l to 0.2 gmol/l and (b) comprises sodium aluminate in a concentration of 0.1 gmol/l to 1.0 gmol/l.
- ingredient (a) comprises a mineral acid selected from hydrochloric acid in a concentration of from 0.1 to 0.8 gmol/l and phosphoric acid in a concentration of from 0.02 to 0.2 gmol/l and (b) comprises alkaline earth metal salt selected from sodium aluminate and sodium silicate in a concentration of from 0.04 gmol/l to 0.4 gmol/l.
- in-situ deposition of aluminium trihydrate was carried out by wicking a yarn/fabric in hydrochloric acid and a solution of sodium aluminate.
- the wicking was carried out by hanging the swatch vertically by means of threads in such a way that bottom edge of swatch just dips inside the first solution kept below. After wicking was complete the swatch was kept in a horizontal position and the second solution was added to the swatch uniformly and dried for 24 hours. The concentration of the solution was determined using the stoichiometry and based on the percentage weight addition of precipitate on the fabric.
- Example 1 the fabric was first wicked under hydrochloric acid followed by sodium aluminate solution to produce aluminium trihydrate particles.
- Example 2 the fabric was first wicked under sodium aluminate solution followed by hydrochloric acid to produce aluminium trihydrate particles.
- Example 3 the fabric was only wicked in hydrochloric acid which could be further treated with sodium aluminate solution to provide a treated fabric according to the present invention.
- Example 4 the fabric was only wicked in sodium aluminate solution which could be further treated with hydrochloric acid to provide a treated fabric according to the present invention.
- Comparative Example A the fabric was untreated.
- the fabrics were soiled artificially with particulate soil and sebum to provide a much reduced reflectance value.
- the fabrics after soiling were soaked in 2.5 g/l commercial detergent solution in water.
- the composition of the commercial detergent used is described in Table 1.
- Three swatches were soaked in detergent solution. After soaking, the swatches were mechanically agitated in a water shaker for 30 minutes. After the mechanical agitation, the swatches were rinsed three times using water. Then the swatches were taken out and dried. This protocol was followed for 6 cycles.
- Colour Eye 7000 A (Gretag Macbeth) instrument was used for reflectance measurements.
- the reflectance of fabric was monitored at the wavelength of 460 nm with UV filter.
- the reflectance value of the original fabric was about 88.
- the reflectance value was measured before the first soiling after the treatment. Each soiling and wash forms one cycle.
- Example 5 the fabric was first wicked under phosphoric acid followed by sodium aluminate solution to produce aluminium trihydrate particles.
- Example 6 the fabric was first wicked under sodium aluminate solution followed by phosphoric acid to produce aluminium trihydrate particles.
- Example 7 the fabric was first wicked in sodium silicate solution followed by sodium aluminate to produce sodium aluminium silicate particles.
- Comparative Example B the fabric was untreated.
- V is the volumetric flow rate (m 3 /s)
- A is the area of the fabric (m 2 )
- K is the permeability (m 2 )
- ⁇ P is the pressure difference across the fabric (N/m 2 )
- ⁇ is the viscosity of air (kg/ms)
- x is the thickness of the fabric (m).
- the air permeability data are given in Table 4.
- Example 9 a fabric of weight 12 g was treated with 30 g of a solution of neutral sodium silicate and 20 g of urea in 300 ml of water and was heated to 95° C. and maintained at that temperature for 4 hours. In this way silica was deposited by the in-situ precipitation method. The fabric was subsequently rinsed in water and dried.
- Example 10 a fabric was soaked in a 15% neutral sodium silicate solution and CO 2 gas was bubbled into it for 4 hours. In this way silica was deposited by bubbling CO 2 gas through sodium silicate solution. The fabric was rinsed in water and dried.
- Example 11 initially the fabric was soaked in 15% neutral sodium silicate solution and then dried in the air for 24 hours. The reaction between CO 2 (from air) and sodium silicate (on the fabric) resulted in silica deposition. The fabric was rinsed in water and dried.
